Lymphocytes (B-cells, T-cells, and NK-cells) are the primary components of the adaptive immune system. In a Differential Count, the lymphocyte percentage helps determine if the body is mounting a response to a viral infection, chronic inflammation, or a hematologic malignancy. It is a fundamental marker for identifying lymphocytosis or lymphopenia.

Why Context Matters
The percentage (relative count) can be artificially high or low if the total White Blood Cell (WBC) count is abnormal. A second opinion is often needed to correlate the 'relative' percentage with the 'absolute' count and the peripheral blood smear morphology to rule out reactive vs. malignant cells.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
